In my experience running a flower shop for fifteen years and filling tens of thousands of orders, honesty flower is the one cut that customers asked about by half a dozen different names before settling on the right one.
Honesty Flower (Lunaria): The Silver-Dollar Plant
The honesty flower has too many names for one plant. Botanists call it Lunaria annua. Old-fashioned gardeners call it the silver-dollar plant. Pinterest calls it dried Lunaria. Crafters call it money plant. Florists call it whatever the customer just called it, then look up which they meant. They are all the same thing: a tall, papery, silvery-white seed pod that looks like a translucent coin and lasts five years in a vase.
What customers usually want to know is which name to use when ordering, where to actually buy it, and whether they should grow it themselves. The honest answers are: any of the names will work at a real florist, the dried pods are sold in three different places (each with a tradeoff), and yes, you should grow it yourself, because Lunaria is one of the easiest cut-flower-adjacent plants in the temperate-climate garden.
What Lunaria actually is
Lunaria annua is a biennial plant in the Brassicaceae family, related (genetically, not visually) to broccoli, mustard, and arugula. The plant grows two to three feet tall, blooms in late spring with small four-petaled purple or white flowers, and then sets seed pods that ripen through summer. The flowers are pretty enough but unremarkable. The seed pods are why the plant has been in cottage gardens for four hundred years.
The seed pods are flat, round, and translucent, about the size of a US half-dollar coin or a UK two-pound coin. As the pods dry on the plant, the outer husks become papery and split off, leaving the silvery-white inner membrane that gives the silver-dollar effect its name. The membrane is durable, weatherproof if kept indoors, and holds the seeds inside until you shake them out.
The plant is biennial, meaning it flowers in its second year. You sow seed in year one, the plant grows a leaf rosette and overwinters, and in year two it shoots up flower stalks, blooms, sets pods, and then dies. The seed self-sows aggressively in cottage gardens; once you have it, you have it for as long as you want it.
Why dried Lunaria became Pinterest-famous
Three things converged around 2018-2020 to make dried Lunaria the most-shared cut-flower-adjacent product on Pinterest. The first was the broader dried-flower revival, fueled by sustainability discourse and the realization that fresh-cut flowers are an absurdly carbon-intensive industry. Dried flowers last years instead of days, ship without refrigeration, and arrive looking exactly the way they will look in your vase.
The second was the Pinterest aesthetic itself. The dominant interior-design palette of that period (white walls, oak floors, cream textiles, brass hardware) wanted a vase accent that was visually structural without competing with the room. Dried Lunaria is silvery-white, almost colorless, and reads as texture rather than color. It fits the palette without negotiating with it.
The third was supply. Dried Lunaria is genuinely cheap to produce and easy to ship. Once a few etsy sellers and farmhouse-decor shops started carrying it, the price dropped, the supply chain matured, and the product became available everywhere from grocery-store floral departments to independent home goods stores. The combination of trend, palette fit, and supply made dried Lunaria one of the small handful of cut-flower-adjacent products that genuinely went viral.
Where to buy it
Three options, with tradeoffs.
Mixed dried bouquet from a national florist (easiest, fastest). Both Teleflora and Proflowers carry dried-flower bouquets that include Lunaria stems alongside other dried elements (eucalyptus, pampas grass, ruscus). The price runs $40 to $80 depending on size. The arrangement arrives ready to display. The downside is you cannot pick the exact ratio of Lunaria to other dried material; you get whatever the bouquet designer chose.
Loose dried Lunaria stems from Etsy or a specialty dried-flower shop (best for the hobbyist). Loose stems run $8 to $20 per bunch of five to ten stems. Quality varies widely; the best sellers harvest at the peak of the silver-dollar effect (right after the husks naturally split, before the membranes start to yellow). Look for sellers who post photos of recent harvests rather than recycled stock photos. Eucalyptus shops on Etsy usually carry Lunaria as a complementary product.
Grow it yourself (cheapest long-term, most rewarding). A packet of Lunaria seeds costs $3 to $6 and produces enough silver-dollar pods for a dozen vases per plant in year two. We cover this in detail below.
How to grow honesty flower at home
Lunaria is one of the easiest temperate-zone biennials. Hardy in USDA zones 4 through 9, tolerates partial shade, indifferent to soil quality, deer-resistant, and self-sows aggressively. Once established, it asks for nothing.
Year one: sow and overwinter
Sow seeds in late spring or early summer (May through July) at a depth of about a quarter inch. Lunaria germinates in 10 to 14 days at soil temperatures above 60 degrees Fahrenheit. The seedlings will form a low rosette of heart-shaped leaves and stay in that form through fall and winter. Resist the urge to clean up the rosette in autumn; the leaves overwinter and feed the spring growth.
Plant in a partially shaded spot with reasonable drainage. Lunaria does not need full sun, prefers some afternoon shade in hotter climates, and tolerates dappled woodland conditions better than most cut-flower plants. The biennial cycle means the planting location should be one you do not need to disturb for two years.
Year two: bloom, harvest, replant
In April or May of year two, the plant shoots up two-to-three-foot flower stalks. Small four-petaled purple flowers bloom for three to four weeks. After the flowers fade, the seed pods form. The pods start green and flat, then turn silvery-tan as they mature through June and July.
The harvest window is the critical detail. Cut too early and the pods are still green; the silver-dollar effect requires the outer husks to dry on the plant. Cut too late and the wind has already torn the membranes. The right window is roughly two weeks long, when the pods are dry, papery, and the husks are just starting to peel naturally. Cut whole stems at the base, bring indoors, and hang upside-down in a cool dry place for one to two weeks to finish drying.
The husks come off easily. Rub each pod between thumb and forefinger; the two outer husks split away with a satisfying papery crinkle, the seeds spill into your palm, and what remains is the inner membrane on its silver stem. Save the seeds for replanting in year three.
Arranging dried Lunaria in a vase
Three things to know before you arrange.
Lunaria is structural, not focal. The silver-dollar pods read as texture and color-balance rather than as a focal point. They work best as the structural backbone of a dried arrangement that includes a focal element (dried hydrangea, statice, dried roses) and a contrast texture (eucalyptus, pampas, dried grasses).
Match stem length to vase height. Lunaria stems stay rigid once dry; you cannot bend them. Cut stems before arranging so the silver-dollar pods sit just above the vase rim at the lowest and reach a height of one and a half to two times the vase height at the tallest.
Lunaria lasts five years if kept dry. Direct sunlight will yellow the membranes within a year. Humidity above 70 percent will warp them. Keep dried arrangements out of bathrooms, away from windows that get direct afternoon sun, and the silver-dollar effect holds for at least five years.
The flower-meaning question
Lunaria has been used in Western flower-meaning traditions to symbolize honesty (hence the common name) and prosperity (hence the alternative name money plant). Neither meaning is universal, both are recent inventions of the Victorian flower-meaning revival, and most cut-flower buyers do not buy Lunaria for the meaning. They buy it for the silver-dollar effect.
If you are giving Lunaria as part of a meaning-based gift (anniversary, milestone), the honesty interpretation is the older and more widely cited one. The Latin etymology runs from luna (moon) to the moon-shaped pods, not from any moral framing.
The DIY harvest from a garden cut
If you already have a garden and want to add Lunaria for next year's vase, here is the abbreviated cycle.
- Order seeds in March or April. Look for Lunaria annua specifically; some sellers also offer Lunaria rediviva, a perennial cousin with similar pods that takes longer to establish.
- Sow in May or June in a partially shaded bed with reasonable drainage. Cover lightly with soil, water in, and forget about them.
- Overwinter the rosette. Do not cut back the leaves in fall. The plant feeds the spring growth from the overwintered foliage.
- Watch for flower stalks in April of year two. When the flowers fade and the green pods form, the harvest is six to eight weeks out.
- Harvest in June or July. Cut whole stems when the pods turn silvery-tan and the husks start to peel naturally. Hang upside down in a cool dry place for ten days.
- Rub the husks off. The silver-dollar effect appears when the outer husks come away. Save the seeds for next year's planting.
One note for households in zone 7 and warmer: Lunaria self-sows aggressively. Once established, you will have new plants every year without replanting. The overwintering rosettes appear in fall about ten feet from the parent plant, mature the following spring, and continue the cycle. Treat it as a forever-plant in those climates.
The fast answer
Honesty flower (Lunaria annua) is the silver-dollar plant. The dried pods are a beloved Pinterest staple because they last five years, photograph beautifully, and fit almost any palette. Buy them as part of a dried bouquet from Teleflora for the easiest path, loose stems from Etsy if you want to control the arrangement yourself, or grow them from a $5 seed packet if you have a partially shaded spot in the garden and patience for a two-year cycle. The plant rewards the patient gardener with a half-decade of vase material per harvest.
